After saving the Moonlit Black Cats guild from a monster attack, their leader, Keita, thanks Kirito and asks him to join their guild, an organized group of players that regularly play together. Kirito accepts the invitation, but hides the fact that his level is twice the average level of the guild. Kirito bonds with his new friends, especially Sachi, who confides in Kirito that she is afraid to die. Kirito assures her that he will protect her, and they will be free one day. On June 12, 2023, while Keita goes to buy a house for the guild, the other Black Cats members decide to earn some money by going to the upper floor dungeons. However, they become trapped in a room with higher-level monsters. Unable to save them, Kirito watches as the Black Cats are killed, including Sachi. When Keita learns of his guild's demise, and Kirito's high player level, he commits suicide. Kirito then receives a final message from Sachi telling Kirito not to blame himself for her death and live strong, which also includes a clip of Sachi singing a Christmas song. (Source: Wikipedia)
